Hello all,
I consider getting a Galaxy S4, but the problem is that the screen backlight flickers, probably in order to conserve energy.
Most people don't even notice it as it flickers very fast (similar to CRT TV flicker), but it annoys me to the point of being a deal breaker.
Is there a way to disable that? Maybe with a custom ROM?

I've owned 3 of these so far (on the 4th... let's not even go there for now)
The newest one seems to be fine overall -- but I'm wondering if this is common among other GTs--
Problem:
Turning off the screen, and then quickly turning it back on causes the backlight to start, but the screen remains black until the power button is cycled again.
Here are the conditions under which I've experienced the problem:
GT 10.1, 32GB, Gray
Screen brightness ~40% and 100%
Lockscreen and Homescreen wallpapers set to Gallery image.
It has happened to me a few times, but not often enough to bother me. There was a topic about this soon after the release and I believe the problem isn't very rare.
I'm going to be at Best Buy later today anyway, so I'm going to see if I can replicate the problem on their display models.
It's quite annoying... Could someone try to see if they have the same issue on their retail model for me? It shouldn't be difficult to. It happens a lot, personally.
Ive been trying to replicate it but no luck. not sure if it matters but I've got a pattern lock screen.

Hi all,
I have a visual disorder known as PMA ( Persistent Migraine Aura). Simpy put, my vision is extremely sensitive to all light forms.
The S4 has really bad backlight flicker, especially in low conditions I can see the flicker. It's really horrible for me as I see it more than the average person would. I couldn't believe it had such prominent flickering from the backlight LED's (low refresh rate?) when I first got my phone; I recently sold my Laptop as it had a poor LED backlight panel.
Now to my question: is there any rom out there that reduces this? Any way of reducing this flicker (increase refresh rate)? It's really making me considering selling the phone
Any help will be appreciated.
Did the maximum brightness change? Used to be when using auto-brightness outside (very sunny), the brightness would kick up to 11.. (brighter then it would be if you used the slider..) I'm not seeing this behavior with kitkat..
Ever since the kitkat upgrade, I can barely see my screen outside! I use my galaxy note 3 on a bike mount, so this is a big deal for me
Anyone else noticed this? Any fixes that don't involve root??

Hi, started this thread to see if anyone had the same problem I'm having with my screen.
I have a Galaxy S4 GT-I9500 (Octa-core variation), it is running 4.4.2, rooted, stock Touchwiz.
The problem is that the screen starts to flicker almost as if it would want to turn off, when in low light conditions and auto-brightness on, it continues to flicker unless I set the brightness between +2 and +5. I can reproduce the issue without auto-brightness setting the brightness to the lowest, one notch above the lowest and there is no flickering. It is noticeable in white backgrounds and also when swiping down the notification center, that's the most noticeable instance but you can see it in the home screen and in any app.
I started noticing it when I had 4.2.2 Jelly bean (rooted), and I updated to Kitkat hoping it would be solved but it is the same, I updated through Kies and rooted, no Factory reset, I want to try that as last resort.
Funny thing I discovered is when I set Juice Defender to control my brightness it does not flicker even in -60% brightness, but when the dimming happens before the screen turns off it does flicker (and the dimming thing is controlled by the OS I think, not Juice Defender).
I wish I could put up a video but I don't have another phone to film it.
Anyone know if this is software or hardware? What can I do?
I'd like to add, that I changed the battery, disabled overlays in developers option, forced GPU rendering, tried Pimp my rom and played with all the settings, checked and unchecked every option in Display settings and it still flickered given the low brightness conditions.
I think I've found the best solution out there for most annoying screen flickering issues... Done a substential amount of digging and finally discovered the app "Twillight" works like a charm by enabling backlight control feature... Try it out first, then thank me and share your experience here ...
Hi guys,
I've been experiencing a strange problem with my N4.
Sometimes when waking the phone back from idle mode the screen gets dimmed. Not all of it though – the status bar and control panel at the bottom won't be affected. It looks like a layer that all of a sudden covers most parts of my screen. Toggling the brightness settings will have an effect on the overall screen only in that it only allows more light through this half-opaque black layer, it won't get rid of it however. I need to reboot the phone in order to get rid of it.
Running a rooted N4 – CWM 6.0.4.7, SuperSU 2.16, KK 4.4.4 (KTU84P)
This has been an ongoing problem for as long as I have the phone, I think… but it seems like it's becoming more frequent. I can't find anything related to this topic on the internet.
Thanks.
